C type purlin roll forming machine

C type purlin roll forming machine

C-section purlins are primarily used in roof and wall structures to provide secondary structural support, working in conjunction with the main steel structure. Therefore, the equipment design places greater emphasis on: forming speed, hole position accuracy, dimensional consistency, and automation level. It is the most widely used specialized forming equipment for C-section purlins in steel structure factories, warehouse buildings, and photovoltaic building projects.

Product description

I. Product Overview | What is a C-Section Purlin Roll Forming Machine?

The C-Section Purlin Roll Forming Machine is a fully automatic cold roll forming equipment specifically designed for producing C-section purlins used in building steel structure envelope systems. With high efficiency, accurate hole positioning, and stable dimensions as its core design objectives, it is suitable for large-volume continuous production.

II. Composition of a C-Section Purlin Roll Forming Production Line

A complete C-section purlin roll forming production line typically includes:

  • Hydraulic or electric decoiler
  • Leveling and guiding device
  • Servo punching system
  • C-section purlin roll forming main machine
  • Cutting device
  • Finished product discharge rack
  • Automatic stacking system (optional based on customer needs) for higher automation.
